8 Claims.

My inventionrelates to improvements in ya lline indicator for sidevvise opening books, and it consists of the combinations, constructions and arrangements hereinafter described and claimed. An object of my invention is to vprovide a line indicator for sidewise opening books which is an' adjustable along the bar.

In the present form of the invention, I show two spring clips that are slidably mounted in a guide bar and these clips are designed to yieldingly engage with one or more pages of a sidewise opening book and to hold the guide bar adjacent to the side edge of the page being copied. The adjustability of the clipsin the guide bar adapts the device to be quickly secured to aV page regardless of the size of the page.

A further object of my invention is to provide 25.- a device of the type described in which the line indicating member comprises a deformable strip. 'This strip is slidably mounted in a carriage which in turn is slidably mounted on the guide bar.

The line indicating member or strip may be bent' 3913 into different curved shapes to conform to the curvature of the page being copied and the strip will hold its shape so that it will be positioned adjacent to-the entire length of the line. l

v-Ialso provide novel meansfor anchoring the faline indicator to the cover of the sidewise opening book and this Will permit the line indicat ing member to be manually moved from line to line Without the guide bar exerting any pulling force on the one or more pages to which itis ";attached. The pulling forceis taken up by the anchoring means. The anchoring means may be secured to another book if desired, rather than to the Acover of the book being copied, and the other book can further act as a support for holding the rst book in the proper inclined position.,

The anchoring means is removably secured to either endof the guide bar and this adapts thel device to be secured to either the right or left hand pages of an openA book.

Other objects and advantages `Will appear in,

' Figure 7 is a side elevation of the anchoringA clip.

In carrying out my invention, I provide a guide bar shown at I in Figures land 2. This guide bar is preferably madefrom a sheet of metal 20 that is bent to form a bar that is ysubstantially squarein cross section. Figure v3shows how Ythe bar'l is provided with a slot 2 along its inner uppervedge and Figure 2 illustrates how the slot 2 extends substantially throughout the lengthl 254 of the bar. y

The' bar slidably carries tWo clips shown at 3 and 4. Both clips are identical to each other and therefore a description of one will suffice.

The clip 3 has'a long arm 5'designed to extend 3 0.'`

under a page 6 in a sidewise opening book 1. The long arm 5 is integral with a bodyportion 8 of the clip and this body portion is substantially square in cross section and is designed toslidably contact With the interior surface of the 35;

bar i. Thebody 8 is longer than the Width of the arm 5, seeFigure 2, and this will give the body a vlength suiiicient to hold the clip against angular svvmging While permitting the clip to be moved along the bar I.l i

The clip has an upper'short arm 9 that is also integral with the body 8 and this short arm extends over the top of the page 6.y Since the, slot 2 in the bar l 'extends substantially through- Ourthe length of the mathe cups 3 and 4 may 45 I ,be moved into any desired position along the bar. This arrangement permits the clips to grip` the page ,6 at any desiredplace. Figure 3 shows the slot 2 as being disposed near the top of the bar and on its inner side. thearms 5 and 9 of theclips close to the top of -the bar and therefore the pageG will beheld close to the bar top.

I Will now describe the line indicating rmeans and this comprises a carriage I0' that is slidable` 55' This l Will position 50 along the bar I. The carriage is shown in cross section in Figure 3 and it will be noted that it slidably engages with the top, bottom and the side wall furthest removed from the page 5. A portion of the carriage also engages with the inner wall of the bar, but this portion does not extend across the slot 2. The outer wall II of the carriage is spaced a slight distance from the adjacent outer Wall of the bar i and a leaf spring I2 is disposed in this space and yieldingly engages with the bar wall in order to frictionally hold the carriage in adjusted position.

The top of the carriage has a spring-retaining member i3, see Figures 2 and 3, with openings Ill in its sides for slidably receiving a line indieating strip I5. A leaf spring i6 is anchored to the top of the carriage iii at Il and extends overr the strip I5 so as to frictionally hold it in adjusted position. The strip is made of material that can be bent and will retain its bent form. I have clearly shown this feature in Figure 3 Where the end of the strip is curved at Ia. It should also be noted from Figure S that the carriage i3 is movable along the bar I so that the strip I5 can move past either or both of the clips 3 and Il, if desired. The bar i5 is shown curved at |50, in Figure 2 in order to conform to the curvature of the portion Ec of the page 5.

It is possible to use the bar l with its line indicating means without resorting to an anchoring means for the bar, but I have found that better results are obtained in moving the line indicating strip when an anchoring means is used. Each end of the bar I is provided with an opening It for receiving the anchoring means. In Figure 4, I show how each end of the bar is closed by means of a plug I3 and this plug has anl opening 2t aligned with the openings IS in the bar. The plug also has a bore 2i for receiving a coil spring 22 and this spring bears against a pin 23 that has its. free end extending a slight distance into the opening 2d. the spring rests against a pin 22a.

The anchoring means itself. consists of a rod 24 provided with a shoulder 25 and a reduced portion 2d. The diameter of the reduced portion is the same as the diameter of the opening 20 and therefore the rod 2d may be secured to the bar i by merely moving the reduced portion 26 into the aligned openings i2 and Z. The shoulder 23 limits the inward movement of the rod. The reduced portion 25 has an annular groove 2l that is positioned in line with the spring-pressed pin 23 when the rod 2d is in place. The spring 22 will cause the pin to enter the groove 2l' and to yieidingly hold the rod 24 against accidental removal while permitting the rod to rotate about its axis. In this manner the rod 24 may be removably secured to either end of the bar I.

The free end of the rod Eil has a circular portion 28, see Figures 4 and 5 for receiving a rivet 29. A second rod 3E is also provided with a circular portion 3E and this curved portion has a'recess 32 formed therein, see Figure 5. A pin 33 is carried by the circular portion 28 and extends into the recess 32, to limit the swinging of the rod Sli about the rivet 29. This construction permits the rod 33 to have a limited swinging movement .with respect to the rod 24.

The rod 3i! has a swivel connection with a clipcarrying rod 34, see Figure 6. The rod 3d carries a casing 35 for rotatably receiving the end of the rod 3B'. The rod 3B has an annular groove 36 which receives a pin 3l carried by the casing.

The other end of In this way, the rod 34 may be rotated with respect to the rod 30.

.In Figures 2 and 7, I show the free end of the rod 34 bent at 38 and swivelly connected at 39 to an anchoring clip dll. The clip 4I) is shown in Figure 2 attached to the cover lb of the book 1. In Figure 1, I show the same clip d secured to the cover of a second book IlI. The book 4I also holds the book 'I at the proper angle.

From the foregoing description of. the various parts of the device, the operation thereof may be readily understood.

The clips 3 and t are first adjusted on the bar I into the proper positions and then the clips receive one or more pages i5. This causes the bar I to be placed close to the side edge of the page.

The anchoring clip :it may now be secured to the book covei edge lh and this Will prevent the bar I from moving longitudinally when the line indicating strip E5 is manually moved along the bar I. The strip i5 is curved to conformV to the curvature of the page being copied and it will hold the shape into which it is bent.

It is possible to secure the device to the left hand page. When this is done, the bar I is inverted and the carriage I@ will cause its strip I5 to extend over the left hand page. The anchoring means is preferably transferred to the other end of the bar and the rod 21S is inserted in the other opening I8. l

When the anchoring means is secured to another book, such as the book ll I, it holds the book 1I-against sipping and the latter book is also supported at the desired angle. It will be noted from Figure 3, that the strip l5 is free to move over the clips 3 and i without interfering with them in any manner. The clips 3 and l5 and the strip I5 are quickly adjustable to any size book page 6. The clips keep the page 6 close to the strip I5 at all times. The strip i5 is deformable and is yieldingly held inadjusted position in the carriage I0.

The line indicating strip i5 has a portion projecting to the right of the member I3 in Figure 2. This projecting portion can be used as a hand grip for moving the indicator along the guide bar i. The strip I5 is also adjustable to accommodate pages of` diierent widths. The aligned rods 34 and 39 have a limited swing with respect to the rod 2li in order to prevent the aligned rods from. swinging into too great an angle with respect to the rod 2li.

Although Figure l shows the guide bar anchoring means extending from the lower end of the guide bar I, it may be advisable to secure the rod 2li to the other end of the bar when it is necessary to apply the anchoring clamp 40 to a different portion of the supporting book 4I The rotation of the rod 2d in the guide bar I, the limited swinging motion between the rods 30 and 2li, the swivel connection between the rods 30 and Sil, and the swivel connection between the rod 3Q and anchoring clip 40, permit a Wide variety 0f positions to be assumed by the anchoring means so that it may be quickly changed to different positions as required by the size of the book being copied and the size of the supporting book. The rod 2li may be inserted into the opening ii! from either side of the bar I.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made Within the scope of the appended claims without departing from the spirit of the invention.
